Open Source

There is certain software that is proprietary in nature and you need to pay to the company owning it to make use of such software. This software is in a ready to use version where the user does not get to the source code and thus cannot run the program with any modifications.

However, there are many open source platforms that make available freeware that comes with code source for use for developers and programmers. For trustworthy sources, please visit this part of the trust directory project.
